I used the Black Horse Arsenal versa pod spacer kit for vepr and versa pod bipod. I know there were problems in the past with BHA but I didn't experience any. One thing I did have to do was get two spacers because the Rhineland hand guard hangs down lower then the bottom of the receiver. Had to drill and tap the receiver but it was easy and they give you the proper taps and drill bits.

Seems that there is very little information on the VEPR Hunter as far as when they first went into production and when they stopped and why did the Pioneer continue and the Hunter stop. Another question, how many Hunters were made?
